Question

The three angles of a triangle are (2x + 10)°, (3x + 10)° & 10°. Find the measure of the two angles.​

Answer 1

Answer:

first angle=70°

second angle=100°

Step-by-step explanation:

2x+10+3x+10+10=180°

2x+3x+10+10+10=180°

2x+3x=180°- 30°

5x=150°

x=(150/5)°

x=30°

by applying the value of x to the evaluation we can get the angles.

Answer 2

Answer:

As the sum of triangle is 180°

(2x+30)+(3x+10)+10°=180°

2x+3x+10+10=180°{Remove Brackets}

5x+20=180°

5x=180°-20

5x=160

x=160÷5

x=32

Ist Angle = 2x+10=2×32+10=64+10=74°

IInd Angle = 3x+10=3×32+10=96+10=106°
